A problem of solver

[Sharonchang]

I've built a trial model via VEDA. And after solving, I found that there lots of errors accured. Expecially, it shows that some of the reporting parameters can not be found, e.g., pra_actl. See attached image. How can I handle these problems? Thanks  a lot!

As far as I can see, you are not able to solve the model at all, because there are GAMS compilation errors. Your screen capture shows that the GAMS run is terminated already at an early stage, due to errors in the input data.

You should check the listing file and see what the compiler errors are, and then try and correct the model data accordingly.

Thanks! I checked the input data again. And I found a problem. In the guidebook, the ANNUAL is permitted in the timeslice, while in my version, versioni 4.3.46, the Annual is not allowed. See attached figures. And in the log files, errors show that

Version: 4.3.46
Model: TIMES LicType: VFTI
1/18/2013 12:25:48 PM
Error while VEDA-FE: Invalid use of Null In Procedure VEDA_FE.modcommonfunctions.Read_DefaultUnit [194]
{94} Invalid use of Null

whether in my version, the ANNUAL is not allowed?

Yes, it looks like a bug in VEDA-FE.  I hope KanOrs will fix it.

However, as a work-around, I guess you could just add some dummy SEASON timeslice there, because such will not be taken into account in the model unless you define a non-zero G_YRFR for it. The ANNUAL timeslice is always included anyway, and will have a G_YRFR=1.

[Gargiulo]

You can use ANNUAL in the Season column and then specify a G_YRFR = 1. This is explained and shown in the VEDA-TIMES GettingStarted.

Thanks!

And I've checked my input file carefully, still got the results as the figure at the first floor. Would you please tell me what's common errors I've made to get the result?

[Sharonchang]

This is the error message shown in the lst file.

Would you please tell me how can I find the place where the error occurs?

Thanks a lot!
